Conflict

It says in the bible that at some point fathers will be against sons and daughters against mothers, and so on in family relationships.  It is a result of some people coming to faith. I call it, "no longer on the same page."  If you have ever lived a life of dissipation, or just shallowness, and then got onto a new path of maturity, you know that you have to drop a lot of the old "friends" with whom you lived such a previous life.  To stay with them would present a conflict.  They would want you to act your old way, because that is how they act.  But you cannot so easily escape family.  If relatives are comfortable with your old ways, the new you just won't fit for them.  To relate to family you will need a new set of friends to help along the way.
